| I'm stumped on copying kernel to /boot. when I go back and read the guide, it says to download and install grub (done that). Then copy /proc/mounts to /etc/mtab. Done that too. Then install grub: I've got that done too. The kernel hasn't changed- at least I think it's version# is still gentoo-2.6.34-r12. The kernel itself has definitely changed, but where do I find out what command it takes, or even what it is in /boot that I'm changing? |

in chroot: | Code: | cd /usr/src/linux
cp arch/x86/boot/bzImage /boot/kernel-2.6.34-gentoo-r12
exit
reboot |
cross fingers
BTW the wget you remarked was you downloading a config file l made, you should now have a file /usr/src/linux/1989688 for use if we need it. |

| Nope, didn't boot. "Please append correct boot option; kernel panic-not syncing: VFS". I can try and copy the screen line by line, if that's necessary. |

in the panic message:
look for a line with driver in it. what driver?
look for a line that says available partitions. what partitions follow?
boot cd, mount gentoo partitions
| Code: | | ls -l /mnt/gentoo/boot/kernel-2.6.34-gentoo-r12 |
what is date time?
| Code: | | ls -l /mnt/gentoo/usr/src/linux/arch/x86/boot/bzImage |
what is date time?
| Code: | | wgetpaste -s ca /mnt/gentoo/usr/src/linux/arch/x86/boot/bzImage |

"Cannot open device "sda3" or unknown block (2,0)" "Please append correct "root"-boot option" then "1048575 sr0 driver:sr"
Hope that sheds some light.

The time seems to be what I have now on the Ubuntu live cd. I went with sudo su --, then did mkdir /mnt/gentoo, but didn't chroot. Changed to chroot and ran wgetpaste. "date", as chroot, shows Sat Nov 13 19:21:19 EST 2010
Tried to reissue the ls -l commands as chroot, got "cannot access-no such file or directory.
And a stopper:
| Code: | ubuntu / # wgetpaste -s ca /mnt/gentoo/usr/src/linux/arch/x86/boot/bzImage
/usr/bin/wgetpaste: /mnt/gentoo/usr/src/linux/arch/x86/boot/bzImage No such file found.

I'm getting punchy. The command we want is
| Code: | | ls -l /mnt/gentoo/boot/kernel-2.6.34-gentoo-r12 |
run with cd booted and both gentoo partitions mounted.
To verify a today after 7 pm date time.
Or just reboot, maybe the last copy copied. |

Still shows Ubuntu time.( "Ubuntu time"? There's a punch line somewhere...)
I'll try a reboot.

Progress! It now gets past all the previous stuff and starts "mounting..." Gets to "mounting devpts at dev/pts", then:
/etc/rc.conf: line 35:syntax error near unexpected token `('
/etc/rc.conf: line 35 `kde-<version>- will start startkde...
*Checking root filesystem..
fsck.ext3: No such file or directory while trying to open /dev/ROOT
/dev/ROOT:
The superblock could not be read.....try running e2fsck with an alternate superblock:

/etc/fstab is screwed up; ROOT BOOT SWAP in the example were to be replaced with actual values
boot cd, | Code: | sudo su --
mkdir /mnt/gentoo
mount /dev/sda3 /mnt/gentoo
nano /mnt/gentoo/etc/fstab |
edit to | Code: | # <fs> <mountpoint> <type> <opts> <dump/pass>
/dev/sda3 / ext3 noatime,notail 0 1
/dev/sda2 none swap sw 0 0
/dev/sda1 /boot ext2 defaults 0 0
shm /dev/shm tmpfs defaults 0 0
|
the rc.conf error: | Code: | | cat /mnt/gentoo/etc/rc.conf |
and post result |

| Code: | # /etc/rc.conf: Global startup script configuration settings
# UNICODE specifies whether you want to have UNICODE support in the console.

Uh...I don't remember setting up X! I selected kde because I like it, but that's the only place during the install that I entered ANYTHING about a window manager, etc. I set up an Arch Linux box for a while, and remember that it seemed as if half the guide was devoted to getting X to work. I didn't see anything in Gentoo even mentioning that something was needed to get graphics going and make pictures appear on the screen! In fact I'm as curious as anything to see what I get when Gentoo boots! I figured I'd have to make X go after Gentoo got to that point, as there's nothing in the guide about it, as far as I can tell.
nano /etc/X11/Sessions/ showed an empty file.
I'm guessing that I need to emerge kde first. |

Emerge at boot gave some error logs. Frome Ubuntu live cd I get " One of the following packages is required to complete your request:
- x11-libs/qt-qt3support-4.6.3 (Change USE: +kde)" Wonder if I have to emerge X-11?
Trying to emerge -av kde-meta, from here:

Have you booted gentoo? If not recommend accomplish first successful boot and clean up any remaining glitches before dealing with X and kde. If you have booted gentoo did you have network?
| Quote: | | Frome Ubuntu live cd |
has me confused. Do I guess correctly that you are emerging kde in the chroot?
Dealing with the problem you raised:
| Code: | | eselect profile list |
should return something like: | Quote: | Available profile symlink targets:
[1] default/linux/amd64/10.0
[2] default/linux/amd64/10.0/desktop
[3] default/linux/amd64/10.0/desktop/gnome *
[4] default/linux/amd64/10.0/desktop/kde
[5] default/linux/amd64/10.0/developer
[6] default/linux/amd64/10.0/no-multilib
[7] default/linux/amd64/10.0/server
[8] hardened/linux/amd64/10.0
[9] hardened/linux/amd64/10.0/no-multilib
[10] selinux/2007.0/amd64
[11] selinux/2007.0/amd64/hardened
[12] selinux/v2refpolicy/amd64
[13] selinux/v2refpolicy/amd64/desktop
[14] selinux/v2refpolicy/amd64/developer
[15] selinux/v2refpolicy/amd64/hardened
[16] selinux/v2refpolicy/amd64/server |
pick the kde profile by number or name | Code: | | eselect profile set default/linux/amd64/10.0/desktop/kde |
to set up use flags for kde. | Code: | emerge --sync
emerge -uND world
|
to update your system to newest stable and with the kde use flags |

Don't know if I have network. Just tries to load (I assume) modules, halts and refers to error logs. If booting Gentoo and getting network working is better, I'll go with that. I'll have to reboot and see what it says so I can get you something to work with as far as what's happening. And yes, was chroot from Ubuntu live cd trying to emerge KDE.
Edit=when I boot, I can log into the terminal.

red is used to highlight my interface names. What interfaces do you have? blue highlights my intrface ip addresses. What ipaddresses are attached to your interfaces if you have UP BROADCAST RUNNING MULTICAST, great news, for which interface.
If you know the ipaddress of your router replacing ?.?.?.? with that ipaddress. What result? If successful the nic is connected to the router. Then If successful the nic can reach the internet. If the nic can work with ipaddresses but not names the problem is lack of domain name service. That is normally a problem in /etc/resolv
BTW ping is a good test. However, will ping forever and convince google that you are attacking them. So use | Code: | | ping -c 2 google.com |
where 2 can be any small number and google.com can be any known web address.

consider the edit parts of my last post suspended, we appear to have no driver in the kernel for your nic
boot gentoo, run: | Code: | | grep -i rt73usb /usr/src/linux/.config |
to confirm or deny
blank response or # rt73usb is not set confirm no driver, rt73usb=y mean some problem connecting driver to nic, | Code: | modprobe -r rt73usb
modprobe rt73usb |
produces what results?
this part of menuconfig changes may have gotten lost:

make menuconfig |

looks like you booted ubuntu instead of gentoo for this; if so you will still have no network and will need a do over after booting gentoo, assuming the reboot works and you are in gentoo without networking,
